Embodiment
Core concept of the present invention is: multimode terminal may be forbidden service access by current persistent district because of reasons such as AC, owing to the reason of service access failure is more, present system does not support to report to the user reason of access failure, and if because of the AC service access that is under an embargo, the user reattempts that to utilize the current network sub-district to carry out service access futile.Current agreement regulation, if terminal is caused service access to be prohibited because of AC by taboo, still reside in former sub-district, attempt inserting next time, and the professional saturation condition duration of General System can pop-off, disabled family may be for a long time can not the enjoy network service, this is rational for single-mode terminal, because there is not other network available, can only attempt inserting again, and for multimode terminal, obviously also unreasonable.And the reason of terminal access failure can't be informed the user in detail, and therefore, if the user does not initiatively select other network, terminal can't select other network to carry out the service access trial automatically.The present invention is directed to AC and prohibited irrational access way in the agreement of back, when determining that when terminal traffic inserts AC is prohibited, no longer under current network, carry out service access, but automatically switch to other network trial service access that this terminal is supported.The present invention realizes that simply cost is lower, but is very easy to the use of user to multimode terminal, has improved the success rate that multi-mode terminal service inserts.Below in conjunction with accompanying drawing technical scheme of the present invention is elaborated.
Fig. 1 is the cut-in method flow chart of multimode terminal of the present invention, and as shown in Figure 1, the cut-in method of multimode terminal of the present invention may further comprise the steps:
Step 101: multimode terminal is resident to the default network sub-district.Multimode terminal is a terminal of supporting many network insertions, at present based on dual-mode terminal, as support global system for mobile communications (GSM, Global System ForMobile Communication), code division multiple access (CDMA, Code Division Multiple Access) dual-mode terminal of system, support the dual-mode terminal of Wideband Code Division Multiple Access (WCDMA) (WCDMA, Wideband Code DivisionMultiple Access) system and gsm system etc.Generally speaking, multimode terminal can select a kind of network to give tacit consent to access network as it automatically, to realize professional access, certainly, also can be by the selected voluntarily access network of giving tacit consent to of user.Need to prove that for different access networks, the subscriber identity module that is distributed is different, therefore, user's service access grade also may be different under the heterogeneous networks.Multimode terminal carries out resident according to the selected default network pattern of terminal.
Step 102: receive the system message of persistent district and resolve the sub-district access control information in the extraction system message.Here, system message mainly is the broadcast message of sub-district, as System information block SIB3 etc.Multimode terminal finish network cell resident after, promptly begin to receive the system message of institute residing network sub-district, extract access control AC prohibition information after receiving system message, and storage.Extract the message that AC forbids in the sub-district, what is inserted other user of level realize forbidding inserting to determine the sub-district.
Step 103:, confirm whether multimode terminal is allowed access to the current network sub-district according to user's access grade.According to the access control information in the cell system message, what whether the access rank of judging current SIM of multimode terminal or usim card belonged to the sub-district forbids inserting rank.The user is by Non-Access Stratum (NAS, NonAccess Stratum) Shu Ru service access request goes to Access Layer (rrc layer), whether AC is prohibited to confirm current business by Access Layer, enter step 104 when being, otherwise directly initiate service request, carry out normal service access flow process to the default network sub-district.
Step 104: resident other network to the multimode terminal support is to carry out service access.When the user is prohibited when suffering the refusal service access because of the sub-district, multimode terminal is initiated the searching request of other network cell public land mobile net (PLMN) of multimode terminal support under the current network pattern, if search, then automatically switch under the network schemer that is searched, carry out the resident of network cell, initiate service access again according to the system broadcasts of current area.
Step 105: when other network still forbids that because of the sub-district access control customer service inserts in the step 104, or can not initiate service access because of other reason such as poor signal the time, multimode terminal enters the pattern of limited-service in former default network, return step 101 behind the some cycles and initiate the resident of network cell again.
